“On May 30 JetBlue Flight 915 from New York’s JFK to San Francisco diverted to Grand Rapids, Mich., following reports of smoke emitting from a carry-on bag holding an electronic device,” JetBlue said in a statement. “The flight landed safely and the aircraft was inspected by maintenance crews before customers continued on to San Francisco.”

There have been persistent concerns over the increased risk of cargo fires caused by large numbers of lithium batteries in the belly of commercial airliners.

According to Mo, who specialises in thermal management systems for batteries, it’s better for the batteries to be in the cabin as opposed to the cargo hold.

“So when (a fire) happens, it’s better to have humans nearby to react and put out the fire,” Mo added.

This is exactly what seems to have happened on board Flight 915.

Fortunately for the JetBlue flight, no injuries have been reported and the flight was able to carry on to San Francisco after the aircraft was cleared by the airport’s fire department.

The Trump administration’s laptop ban has been in place since March and covers non-stop flights to the US from 10 airports located in eight countries in the Middle East and North Africa. The Department of Homeland Security is evaluating an expanded ban that would include non-stop flights from Europe. However, no formal decision on an expanded ban has been made.
